I have a Fedora 12 Desktop machine running at a remote site and have no keyboard not a screen connected to it. After rebooting it remotely I was surprised to learn the machine did not come back up again. (It did when I tested it while I was on site).

View 1 Replies View RelatedLast week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.
Is it possible to like have SMS sent to your cellphone when the server crashes or a process on the server dies?
View 4 Replies View RelatedJust wanted to share this with anyone wanting to know.If your headless server crashes, GRUB2 (at least on Ubuntu Server) is designed to force the GRUB menu to load up next time it starts up, which means you are locked out of SSH until someone physically makes a kernel selection on the PC.To prevent this do the following change to your grub.cfg file.#nano /boot/grub/grub.cfg
I was looking for a solution for this for a long time and found no hel with google. Let me know if there is a better way.I aware this file will get overwritten and need reediting if the Kernel gets updated.

I would like to monitor a RedHat via snmp. I would like to make available data via snmp. The data that I would like to graph are only present in logs file. Is it possible to parse data from applicative logs and have them available for my cacti server via snmp? I already monitor CPU, mem, and others with cacti using the standard MIB.What would be the logical step I would need to achieve that?

I'm running the current release of Debian with the 2.6.26-2 kernel. This is an upgrade from an older (2.4 kernel) series redhat release. One of the things I had working in the older system was a dns server with accompanying monthly update of the root hints file. I tried working through a dns how-to to set this up again, but it seems much has moved around since I last played with this. All of the files listed in the how-to are not where it says they should be. I am looking for a better reference on keeping the dns server running with current server information.

While im looking at my smtp server log at /var/log/maillog, im having these two errors for which im unable to find the reason.
1)Could not open inline file /etc/MailScanner/reports/en/inline.sig.txt, No such file or directory
2)did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
I am not seeing what i am doing wrong here, but here goes:
From my server I need to run a command for backup on 25 remote servers (through a script). Now I have pushed the public keys for remote ssh connectivity on all of them and it works ( I can push files using rsync without the need to enter passwords on the remote servers), howver, I need to run the following command:
ssh odsadmin@10.139.111.1 'cp -a /var/www/life /var/www/life-v4'
when I run this command, I keep getting asked to enter the password, I even tried putting sudo in front of the cp, but still get the request to enter the password.
I currently have a centos 4.4 I believe running with a 250GB hard drive. I want to make an image of that hard drive. I have tried removing the drive and connecting it to my windows pc using an adapter that would allow my windows machine run the hard drive as it was a regular external hard drive. Of course windows doesn't reconize that drive since it is linux partitioned. I am thinking that I need to have the hard drive inthe box I am wanting to copy and put in a blank drive in the box that I want to copy to. And boot from a live CD and use cat or dd to copy it. I have seen the commands before bust I am thinking this is the only way. Basically I am wanting to have a duplicate of the drive and build a whole new server that is already all setup.I will just change the host name and assign it another Public facing UP. Is this correct? Oh, and the new server will have different hardware. Might even be AMD or intel different from source or destination.
View 12 Replies View RelatedI have a wordpress blogging server up and running and i've also got nagios monitoring the speed of webpage download etc.The thing is a couple of weeks ago nagios alerted me that the blog was returning pages really slow loading, when i went to the blog homepage for me also it was very slow. After about 30mins of http connections some finally loading and some not nagios stopped reporting issues, but thats not the end of the story, the graphing of speed i've got set-up on nagios shows quite clearly that ever since that big slow down the pages take avg of extra 2-3 seconds to load. However nothing drastic has changed and the datasize of the page hasn't really changed at all (also monitored).
During that weird period I carried out checks on the server itself like top, free -m, netstat (looking for maybe DOS attack number of connections), looked at mysql see if that was running slow and what processes it was running, checked on number of http processes see if they had ramped up, checked on php and web server errors see if they had increased some what as well. None of these things turned up anything noticeable to be causing such slow blog response.Now its still that average amount high and i'm lost at why this could be? Its niggling at me that something may have got in but i've taken several security steps to try and lock down the wordpress install etc.
is qmail server running in the secondary office and it was working fine. yesterday qmail suffered some problem.i came to know about the problem today.now after troubleshooting and looking into the server, the qmailclt stat commands shows that all services are working and there is nothing going crazy in the server.

View 1 Replies View RelatedI just upgrade my desktop to F12 and using it for few weeks now..Everything seems working fine except X server crash on me often.
Anybody out there have the same problem?
Need a work around solution for this.
Attattched a copy of Xorg.3.log.old for reference.
My system is as follow:
Intel P4 2.26Ghz
Kernel 2.6.32.10-90.fc12.i686.PAE
memory 1G
i did a fresh installation of Fedora 15 x64 with Gnome3.
Whenever i start LibreOffice the X server or gdm crashes and i get to the login screen of gdm.
Does Libreoffce have a log file? There are so many Xorg/gdm log files, i don't find anything...
"system crash" means that:(1)I can ping it , but can not connect to it (via ssh or http or anything else)(2)the major role of that machine is to run a web application written in java, every 3 weeks(almost that), the users inform us and say they can log in that web application , and we find the situation just like (1) says.When this happen , we can only restart the machine by pushing the power button.(It's sad !)I've try to read all the log files located in /var/log but find nothing interesting.

Above message is from /etc/httpd/logs/error_log.1. Saturday morning I reinstall my server. After finish, no error. I can access my HTTP server. Monday morning it has crashed. I don't know what is the meaning about this message.
I have a server running Ubuntu that is running out of space. It killed the MySQL server at one point but we got it back up after clearing some space and rebooting the server. However I would like to extend the space we have on the server. Can I connect a USB drive to the server and just us that? The server supports about 8 web developers. My other thought was to add a NAS device to the network and use it. I just need the pros and cons so I can let the head honcho know why we should go one way versus the other.
The current system is running without a gui at this time. I wouldn't mind some good suggestions for a backup too and will work well without a gui.
Aprox. 1 time per day / every two days hangs the x-server. It hangs a few secs then is being killed and restarted. A popup window in the task bar tells me the restart of the x-server. After that about 15 sec. I can continue to work but sometimes the gtk2 apps lose their integrity thus I have to restart by logging off and in again.

I think I've totally destroyed my Suse install, but I have no idea what happened.
I was running Yast's "Create a backup" utility and my screen totally went black and kicked me to the login screen. I was unable to log in, except to a terminal.
So, then I tried to restart X (by typing startx) and I get "Fatal server error: Server is already active for display 0"
I've tried running the repair utility, and it doesn't work. Through a number of commands, I was able to start up a second X session, but that wasn't really much help.
I have been having problems with Xserver crashes (goes into low graphics mode). On inspection of my .xsession-errors file, I get X IO fatal errors 5, 11 and/or 104.
